Gerät zur Messung der elektrischen Spannung (W)

a volmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit.

Wechselstrom

often shorten with "AC". Electric current which reverses at regularly recurring intervals of time and that has alternately positive and negative values

Amper (Stromstärke)

SI unit measuring the electrical current.Symbol A

Gleichstrom

foten shorten DC

Ohm (elektrischer Widerstand)

SI measuring unit of the electrical resistanceSymbol: Ω

Isolator

A material or a substance that doesn't conducts electricity i.e. doen't allow the passage of electroncse.g. wood, plastics, most of the ceramics

Statische Aufladung

term referring to the amount of electric charges resting in an object

Stromspannung

refers to the difference of electrical potential between two points in an electric circuit.

Volt (elektrische Spannung)

SI derived unit measuring the difference in electrical potentialSymbol: V

Stromkreis

path for electric components

Verstärker

Generally any device that changes, usually increases, the amplitude of a signal

Generator

type of generator, which converts mechanical energy (often rotation) into alternating current. It is found in most of the car connected to a rectifier in order to provide powered devices and the batt…

electrical storage device consisting of electrochemical cells that transform chemical energy into electricity

wire of different length and thickness which carries power or/and datae.g. high voltage wire, copper cable, fibre optics cable

Sicherung

safety device which protects an electric circuit from an overcurrent.

Kabelschuh

protection around an electric cable, which is insulating against impedance, humidity, dust etc...

Leuchtmittel/Glühbirne

Lightening part of a lamp, which actually converts electricity into light and heat. It is an incandescent part of a lamp in which a tungsten filament or other kind of metal filament wire is heated

Stecker

Male electrical connector mounted at the end of a cable in order to match with a female socket and to provide a power device with electricity

Relais

electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays.

It restricts the flow of the current

Halbleiter

Material or substance which conducts

Sensor

Device that detects a physical quantity such as a change (in temperature, proximity, pressure, light intensity) and converts it into a signal which can be read by an observer or by an instrument.

Schalter

electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another.

Wandler

device, which converts an energy form into any other form e.g. device in which electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, …

Transformator

passive component that transfers electrical energy from one electrical circuit to another circuit or multiple circuits through electromagnetic induction.
